GLOBE CLOCK.

Application filed March 13, 1924. Serial No. 698,933.

To all whom. t muy concern.'

Be it known that I, MICHAEL COMFORT, a citizen of the United States lof America, residing at Plantsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Imp-rovements in Globe Clocks, of whic-h the following is a specification.

This invention relates to certain new and useful improvements in clocks and has for its primary object to provide a clock wherein the clock casing is of spherical formation and is supported at the equator or transverse median line thereof.

Another object of the invention is to provide a clock of spherical formation wherein a. central transverse disk plate rotatably supports adjacent edges of hemispherical casing sections with the casing sections reversely rotatable through the medium of clock mechanism, one section indicating time in minutes while the other section indicates time in hours.

With the above and other o'bj ects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the accompanying drawings, wherein like reference characters designate corresponding parts throughout the several views,

Briefly described, the present invention aims to provide a clock wherein the clock casing is of spherical formation embodying upper and lower hemispherical casing sections that are rotatably supported at their meeting edges upon a central disk plate. Clock mechanism. supported upon the disk plate within the connected casing sections has certain gears of the clock train mecha.- nism meshing with circular rack teeth upon the inner faces of the casing section, the gear ratio causing the upper hemispherical section of the clock casing carrying minute indicia to travel in a complete revolution while the lower casing section providing the hour indicia travels one-twelfth of a circle. The central disk plate has an exposed annular flange that carries indicator points directed toward the minute and hour indicia so that accurate time may be read at the transverse median line of the. clock casing.

Referring more in detail to the accompanying drawings there is illustrated spherical clock casing embodying a central disk plate 1 with which the meeting edges of upper and lower hemisplierical clock casing sections 2 and 3, respectively, are associated. The disk plate l is outwardly arched at its peripheral edge as at 4L and carries upwardly and downwardly extending flanged edges 5 and 6 while the meeting edges of the upper and lower casing sections 2 and 3 are angular-ly directed inwardly as at 7 to extend parallel with the adjacent faces of the disk plate 1 as clearly shown in Fig. 3. The connecting means between the disk plate l and the casing sections 2 and 3 includes angle clips S secured as at 9 to the disk plate with their outer ends freely enclosing the angle edges 7 of the casing sections, bearing balls 10 being interposed between the casin flange 7 of the casing section 2 and the disk plate l and between the flange 7 of the lower casing sect-ion 3 and the associated angle clips 8, as shown in Fig. 3, for the purpose of reducing friction and permitting free rotation of the casing sections. Access to the interior of the connected casing sections 2 and 3 is facilitated by the provision of hand entrance openings at the. vertical axis of the casing sections 2 and 3 that are closed by threaded arched disks 11 of a curvature coincident to the curvature of said casing sections and as clearly shown in Figs. 1 and 3. The suspension means for the clock casing includes the provision of outwardly directed arms 12 and 13 to which suspension chains 14 are attached for suspend-ing the clock casing in any convenient manner.

rThe clock mechanism is disposed within the casing sections and supported upon the disk plate 1 adjacent the bracket arm 13 and embodies a base plate 15 directly mounted upon the upper face of the disk plate 1 and spaced from the upper plate 16 by the post 17, this yconstruction being clearly shown in Fig. 3. The main shaft 13l of the clock mechanism has the main spring 19 associated therewith while a bevel pinion 20 fixed to the lower end of the sha-ft 18y extends into the cutaway portion 21 formed in the disk plate 1. A winding stem 22 is journaled in the opening 23 formed 1n the disk plate lthat communicates with the cutaway portion 21 and a beveled pinion-24 secured toI the inner end of the winding stem 23 within the cutaway portion 21 meshes with the bevel pinien 2O u on the lower end of the shaft 18. The brac ret arm 13 is of tubular 'formation as shown in Fig. 6 and the winding stem 23 extends thereinto to be engaged by the wrench end 25 of the winding key 26 shown in Fig. 7. The clock mechanism further includes a bearing .27 supportedupon the lower face of the disk plate 1 and depending therefrom having a shaft j ournaled therein thatis' in 'gear coin;V municat'ion withwthe shaft 18, a pinion v28 associated with the shaft in thebearin'g 27 meshing with a relatively large gear 29 secured to a 'shaft journale'd in the bearing 30 depending vfrom the disk plate with the gear 29 meshing with a circular series of vrack teeth 31 formed upon the inner face of the casing section 3 adjacent the disk plate 1 as clearly shown in Fig. 3, the speed of rotation of the casing section 3 being reduced by the gear ratio as described. A shaft 32d journaled in the plates 15 and 16 has gear connections with the shaft 18 and has a. relatively large gear secured thereto that is in mesh withf the pinion 34 fixed to a shaft journaled in a bearing 35 depending from the upperl plate 16, the pinion 34 meshing with a circularI series of rack teeth 36for'me`d upon'the inner face of the casing section 2 adjacent the upper side of the disk plate 1. From the above description of the clock mechanism, it will be understood that the lower casing section 3 revolves in a clockwise movement while .the upper casing section 2 revolves in a counter-clockwise movement, and by the gear ratio, the upper casing section is caused to travel in one complete revolution while the lower casing section revolves one-twelfth of a revolution. Alarm devices 37 are associated with the clock mechanism and may be of a conventional type for striking hours and half hours.

rlhe o-uter face of the casing section 2 adjacent t-he peripheral edge 4 of the disk plate is provided with a circular series of minute graduations 3S having minute numerals 39 associated therewith while the casing section 3 has hour graduations 40 arranged in a similar manner vand with v which hour numerals 41 are associated. The peripheral edge 4 o-f thedisk pla-te 1 carries indicatorv points 42 and 43 associated with t-he minute and hour graduations as shown in Figs. 1 and 3 so that accurate time may be obtained.

From the above detail description of the clock and its associated mechanism, it is thought that the construction and operation thereof should at once be understood, it being noted that the gearing train of the clock mechanism causes the upper and lower casing sections 2 and 3 to revolve in opposite directions, the gear ratio for the upper section causing the saine to travel in one complete revolution indicating minutes while the gear ratio for the lower casing section causes the latter to revolve onetwelfth of a revolution during the Vsame period of time for indicating one hour. The minute and hour graduati'ons 318 and 40. upon the outer faces of the casingsec-tio'ns whenviewed in connection with the indicator points 42 and 43 will give the accu; rate time and,V a clock of extremely novel appearance and practicalility 'is herein pra vided. The winding 'of the 'clock mecha nism is accomplished by inserting the key 26 in the tubular bracket arm 13 for engag ing the winding stem 23 and lthe alarm mechanism may be associated with the main spring 19 for sin'iultaneously winding the same.

While there is herein shown and described the preferred embodiment of the present invention it is nevertheless to beunderstood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
